WELL-DRILLING APPARATUS.

Specification of Letters Patent.

Application led July 6, 1914. Serial No. 849,(l82.

To all 'whom t may concern.'

Be it known that I, WILLIAM M. KEGK, a citizen of the United States, residing at Coalinga, in the county of Fresno and State of California, have invented certain new and useful Improvements in Well- Drilling Apparatus, of which the following is a specification.

This invention relates to well drilling apparatus and has particular reference to power Wheels or drums for lifting and lowering tubing or the like, and the operating connections between the same and a source of power. y

Heretofore the withdrawing or positioning, of light weight tubing. or casing within a well has been a slow and tedious operation owing to the slow operation of the calf wheel necessitated by the heavy materia-l which the same is required to handle and the constant speedof thev power shaft.

The present invention has for one of its objects to provide a connection between the power shaft and the calf wheel, whereby the rotation of the calf wheel may be changed without varying the speed of the power shaft, thereby providing a slow speed of rotation for the calf wheel when handling heavy loads and an accelerated 'rotation when it is desired to handle light loads.

Another' object of the invention is togenerally improve-the construction of the calf wheel per se. Y

Vith the above mentioned and other objects in view, the invention consists in the novel construction and combination ofparts hereinafter described, illustrated in the accompanying drawings andpointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the ade Vantages of theinvention.r

To more fully comprehend the invention, reference is directed to the accompanying sheets of drawings, wherein- Figure l is a substantially central hori- Zontal section showing my improvements in a preferred embodiment. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a vertical section on the line 3-3 of Fig. 1. Fig. 4 is a detail of construction on the line -lf-l of F ig. 3, showing the mannerv of connecting the high speed sprocket wheel to the calf wheel.

Referring more particularly to the several views ofthe drawings wherein like letters of reference designate corresponding parts throughout the several views, I show a supporting frame 10 providing bearings 1l and 12 for'tlie gudgeons 13 and 1A respectively of the calf wheel construction.

A wheel head A15, in addition to the gudgeon 14, comprises a series of tangent spokes 16 shown as eight in number and secured at their outer ends to a rim 17. lThe drum portion 18 of the wheel is made perferably of a pair of concentric inner and outer tubes 1,9 and 2,0, the spacepbetween the walls of the tubes being filled with cement or some other suitable material adapted to become solid or hard after being set. The hub or gudgeon 111 is provided with a counteriiange 22 which receives the adjacent end of the tube 20 and also is provided with a central annular lip or flange 23. which is inserted into the end of the ,inner tube 19, making a rigid end connection for the barrel or drum 18. A series of bolts 2li shown as four in number pass through the spokes, hub and drum structure, certain of the bolts being at right angles to the others, making a rigid structure. Atr the other end of the drum 18 the gudgeon or hubl 13 constitutes and carries a winch 25. which has characteristics similar to the other gudgeon with respect to the fastening means for theends of the tubes 19 and 20. I employ, however.preferably only two locking bolts 24: at this end of the drum.

I provide a pair of sprocket wheels 26 and 27 secured upon the head 15 and coaxial therewith. Surrounding the wheel 17 and against which the sprocket wheel 26 bears is a metallic reinforcing or strengthening ring, which is of slightly smaller diameter than the sprocket wheel but acts to strengthen or retain this sprocket wheel in position at all times. The sprocket wheel 26 is secured by means of bolts 28 direct to the rim 17 The sprocket wheel 27, however, is provided with a series of lugs 29 having faces applied squarely against the outer faces of certain of the spokes 16, and through said lugs the smaller sprocket wheel issecuredby means of bolts 30 to the spokes. As shownparticularly in- Fig. 1, the spokes are wider than the rim 17 and they are re- Patented Apr. 11, 1916.

cessed as shown at 16 on the side adjacent the wheel 27 so as to give a n eat and substantial seat for the wheel 27 and to provide v sufiicient clearance for the sprocket chain 27EL operating over said wheel. The sprocket chain 26a operating over the larger wheel is spaced, therefore, laterally from the plane of the chain 27a, the two sprocket wheels being arranged on opposite sides of the head 15. rThe heads of the bolts 28 are preferably countersunk in the rims 17 to prevent any interference between the same and the chain 27a.

At 3l I show a power wheel of any suitable construction and adapted to be operated from any suitable source of power at a substantially uniform speed. Said power wheel is secured to a power shaft 32 substantially parallel to the aXis of the calf wheel and mounted in bearings, one of which is shown at 33. A pair of sprocket wheels 3a are mounted loosely upon the end vof the shaft 32 outside of the bearing 33. The inner or adjacent faces of said sprocket wheels 34:

are preferably dished or concaved so as toY provide a maximum space between them for the operation o f a clutch sleeve 35 which is splined to the shaft. A yoke 36 cooperates with the clutch sleeve 35 and is provided with a rock shaft 37 and lever 38 for manipulating the clutch'so as to cause either of the wheels 34 to be operatively connected to the power shaft 32 while the other sprocket wheel 34C is permitted to run idly around the shaft. rlhe aforesaid sprocket chains 26a vand 27a have constant engagement with the wheels 3ft and the calf wheel sprocket wheels already stated. With the power shaft 32 operating at certain-speed, if the drum 18 be operated at a correspondingspeed, the clutch 35 will be shifted so as to positively drive the wheel 27 from the chain 27a in either direction. For slower work, as, for instance, during` the manipulation of heavy tubing or the like, the clutch will be shifted in theY opposite direction, causing the control of the drum 18 to be had through the larger sprocket wheel v26 and its chain 26a, and at a slower speed corresponding to the difference in size between the two wheels 27 and 26.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. In a device of the class described, the same comprising a pair of hollow hubs, means to support the hubs in almement with each other, a drum connecting the hubs, the said drum 'comprising a pair of concentric tubes spaced from each other and cooperating with concentric flanges formed in the hubs, the space between the tube being filled with concrete, a controlling head at one en d of the drum, said head comprising a series of spokes arranged tangentially to the adjacent hub, a series of bolts clamping the spokes to the hub, a rim surrounding and connected to the spokes, the spokes being wider than the rim and recessed to form a seat, a sprocket wheel secured to said spokes in said seat on one side of the head, and a sprocket wheel of different size secured to the opposite side of the head.
